The Transportation Security Administration (TSA) has long turned a deaf ear to criticism and complaints. Whenever its groping of toddlers sets the country howling, the TSA responds that employees “followed proper … procedure.” Ditto when they inspect a 95-year-old invalid’s diaper or drench a survivor of bladder-cancer in his own urine — twice. Last week they even searched trucks and busses in Tennessee to huge outcry nationwide and a sharp rebuke from the heroic Ron Paul. But you can bet such opposition will only increase the number of these internal checkpoints.

Why is Mahmoud Abbas, the Palestinian leader, determined to prevent Jews from living in the new independent Palestinian state? After all, it would solve the settlement problem if Jews were permitted to become citizens of Palestine. But that would require the new state to be democratic. It would have to honor human rights and would have to permit the Jews to vote. It would have to become as secular and democratic as Turkey, where Jews have lived for centuries.

Thomas SowellBack in the 1920s, the intelligentsia on both sides of the Atlantic were loudly protesting the execution of political radicals Sacco and Vanzetti, after what they claimed was an unfair trial. Supreme Court Justice Oliver Wendell Holmes wrote to his young leftist friend Harold Laski, pointing out that there were "a thousand-fold worse cases" involving black defendants, "but the world does not worry over them."

Dennis BehreandtI have a theory about the canary in the coal mine. I expect that before it died of asphyxiation, it would panic and chirp loudly and vigorously at the prospect of its coming demise. It would then fall silent, and pass out, and its change in behavior would warn the miners that the air in the mine had become foul.

The use of canaries in coal mines to warn miners of the danger of accumulating noxious vapors is not just an "old wives' tale." As recently as the 1980s, miners in the UK used the birds to warn of danger. The practice was described by the BBC, which noted that, beginning in 1911, tradition held that two canaries should be "employed by each pit."

It’s 1943 and you find yourself in Germany. A Nazi officer is pointing a gun at you and demanding that you hop on a bulldozer and use it to bury hundreds of Jewish families who have been shot and are piled up in a huge pit. But among the dead are some individuals who are still living, crying out for mercy. What would you do, knowing that if you refuse to bury these people alive you will be gunned down yourself?
